btrfs: drop unused parameter iov_iter from btrfs_write_check()

The parameter 'from' has never been used since commit b8d8e1f ("btrfs: introduce btrfs_write_check()"), this is for buffered write. Direct io write needs it so it was probably an interface thing, but we can drop it. Reviewed-by: Anand Jain <[email protected]> Signed-off-by: David Sterba <[email protected]>
